Hairstyling device

A hairstyling device comprising:

• a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to a tress of hair of a user via the hair-contactable surface by movement of the hair contact member along the tress of hair between a first end of the tress and a second end of the tress;
• sensor equipment configured to generate a sensor output dependent on movement of the hair contact member;
• and
• a controller configured to:
• receive the sensor output from the sensor equipment;
• determine, based on the sensor output, that the hair contact member is moving along the tress from a first end of the tress towards a second end of the tress, comprising determining a displacement of the hair contact member from the first end of the tress;
• determine, based on the sensor output, a speed of the hair contact member;
• based on the determined displacement and the determined speed, control heating of the hair contact member to cause the operating temperature of the hair contact member to change as the hair contact member moves along the tress from the first end of the tress towards the second end of the tress;
• and
• cause the operating temperature of the hair contact member to increase at a rate dependent on the determined speed.

A hairstyling device comprising:

• a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to a tress of hair of a user via the hair-contactable surface by movement of the hair contact member along the tress of hair between a first end of the tress and a second end of the tress;
• sensor equipment configured to generate sensor output indicative of current use of the hairstyling device;
• and
• a controller configured to:
• determine that the hair contact member is moving along the tress from a first end of the tress towards a second end of the tress;
• based on the determining, control heating of the hair contact member to cause the operating temperature of the hair contact member to change as the hair contact member moves along the tress from the first end of the tress towards the second end of the tress;
• and
• cause the operating temperature of the hair contact member to increase at a predetermined rate as the hair contact member moves along the tress from the first end towards the second end.

A hairstyling device comprising:

• a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to a tress of hair of a user via the hair-contactable surface by movement of the hair contact member along the tress of hair between a first end of the tress and a second end of the tress;
• sensor equipment configured to generate sensor output indicative of current use of the hairstyling device;
• a heating element operable to heat the hair contact member;
• and
• a controller configured to:
• determine that the hair contact member is moving along the tress from a first end of the tress towards a second end of the tress;
• determine whether the hairstyling device is being used according to a first styling behaviour or a second, different styling behaviour;
• control heating of the hair contact member, by controlling the heating element, to cause the operating temperature of the hair contact member to change as the hair contact member moves along the tress from the first end of the tress towards the second end of the tress in dependence on whether the hairstyling device is being used according to the first styling behaviour or the second styling behaviour.
